Abstract

        In this paper, we address the joint design of the wireless backhauling network topology, as well as the frequency/power allocation on the wireless links, where nodes are capable of full-duplex (FD) operation. The proposed joint design enables the coexistence of multiple wireless links at the same channel, resulting in an enhanced spectral efficiency. Moreover, it enables the usage of FD capability when/where it is gainful. In this regard, a mixed-integer linear program is proposed, aiming at a minimum-cost design for the wireless backhaul network, considering the required rate demand at each base station. Moreover, a retuning algorithm is proposed, which reacts to the slight changes in the network condition, e.g., channel attenuation or rate demand, by adjusting the transmit power at the wireless links. In this regard, a successive-inner-approximation-based design is proposed, where, in each step, a convex subproblem is solved. Numerical simulations show a reduction in the overall network cost via the utilization of the proposed designs, thanks to the coexistence of multiple wireless links on the same channel due to the FD capability.
